maxill. palpi semiglobose, these otherwise the same as in the 

 former. Thorax and elytra of S. alatus, the former, however, 

 larger, rounded at the posterior margin, and with four basal 

 impressions, the later slightly truncated at the apex and 

 with slight sinuosity in the truncature on either side of the 

 suture. Scutellum very small. Legs with the tibiae slightly 

 bent at the base, the apex as in the former ; tarsi with joints 

 1-4 gradually decreasing in size, first pair contracted and 

 furnished with brushes on the inside. The two posterior legs 

 inserted rather distant from each other, the basal part of 

 abnormal construction ; the trochanters much elongated 

 and incrassated at the tip, whilst the femora at the place 

 of the juncture rather abruptly narrowed, bent, and slightly 

 compressed, — they being, at the same time, thinner than the 

 adjoining apex of the trochanter ; the constriction very 

 striking.

An anomalous species, especially with regard to the antennae 

 which are much less approximated at the base than those of the 

 rest of the species belonging to this group, and with regard 

 to the two posterior coxae, which, on the contrary, are more 

 approximated than in any of the species just referred to. The 

 insect is of the light brown color of the two former, but larger 

 and more depressed. The head is strikingly large and heavy, 

 of the width of the thorax, in its hind part, which is strongly 

 transverse, the oval form is prevailing over that of the square. 

 Eyes small. Antennae inserted under two strong protuber- 

 ances rather than under a ridge, their club four jointed, joints 

 3-7 forming an inwards-bent section of a circle, joints 8-10
